Notes. ^(a)From the SIMBAD astronomical database (Wenger et al. 2000). ^(b)IA (poorly studied variables of early spectral type), L (slow irregular variables), GCAS (γ Cassiopeiae type), ACYG (α Cyg type), SPB (slowly pulsating B stars), and S Dor (S Doradus type) (classification taken from Lefèvre et al. 2009). The question mark means that the classification was based on a new period determination or that the type could not be clearly identified from the HIPPARCOS light curve. ^(c)Lefèvre et al.
